CAN-l-ILLING MACHINE.

SPECIFICATION forming part Of Letters Patent NO. 516,326, dated March13, 1894. Application filed March 1, 1893. Renewed February 5, 1894-Serial N0. 4:99.210. (N model.)

To all whom it may concern.-

Be it known that we, HARTLEY C. BAXTER, of Brunswick, and HENRY R.STICKNEY, of Portland, county of Cumberland, State of Maine,

have invented new and useful Improvements in Can-Filling Machines, ofwhich the following, taken in connection with the accompanying drawings,is a full, clear, and exact description.

This invention consists in an improved organization of a machine whichis convenient and efficient in its operation, and passes the cans to thefiller,injects sirup into the cans in transit, wipes the tops of thefilled cans and r5 stirs the contents of the cans by means of a singlelever operated by the person in charge of the machine, all ashereinafter more fully described and set forth in the claims.

In the annexed drawings Figure lis an end elevation of ourimprovedcan-filling machine showing its connection with the cooking apparatus.Figs. 2 and 3 are side elevations of said can filling machine showingthe same in two of its operative positions. Fig. tis atop 2 5 plan viewof the same. Fig. 5 is a vertical transverse section of the stirrertaken online at, w, in Fig. 3, and Fig. 6 is a vertical transversesection of the can-lifter taken on line y, y, in Fig. 4.

Similar letters of reference indicate corresponding parts.

A represents the filler which is attached to the end of the cookingcylinder -B which may be of any suitable and well known con- 3 5struction, preferably of the form shown in the Patent No. 202,979,granted to Edward P. Bates, April 30, 1878. Said cylinder being providedin its interior with a spiral conveyer which forces the cooked substanceinto the filler, which latter is also in this case provided with avertical spiral conveyor, not necessary to be here shown, by whichconveyer the cooked substance is forced from the filler into the canplaced under the discharge spout of the filler. Beneath the filler andextending laterally therefrom is the can-guide aover one end of which isarranged a ring or suitable can-chute -afor the reception of the cans tobe filled. Under said can-chute is the can-pushing bar -b which ismovable 5o lengthwise of the can-guide 'a and is provided on top of itsouter end portion with a platform bby which it supports the cans in thechute a while said bar-b pushes the bottom can from under the chute andtoward the filler. Said platform has on'its side facing the filler adownwardly extending shoulder b" by which it pushes the cans asaforesaid.

Directly under the filler A is the canlifter -cwhich raises the can fromthe canguide sufficiently to cause the discharge spout of the filler toenter into the opening in the top of the can and charge the can with thecooked substance. Said can-lifter is held normally with its top flushwith the top of the can-guide, by means of a spiral spring c'surrounding the downwardly extending stem c of the lifter and bearingwith its opposite ends respectively against the under side of thecan-guide and against a collar attached to said stem.

The described can-pushing bar b and can-lifter c are both operated bymeans of one and the same lever -O which is operated by the person incharge of the machine and also actuates all other mechanisms of themachine as hereinafter explained. The lever -O is pivotally mounted on ashaft D extending across the machine some distance beneath the can-guide'aand I journaled in brackets D- rigidly attached to or integral withthe bottom of the canguide, which latter constitutes part of the frameof the machine.

To the shaft D- are fastened two rockarms FF- which are thus pivoted incommon and caused to move in unison. The rock-arm F is extended upwardand pivotally connected to the can-pushing bar -b' at which point thelever, 0, is provided with two bearings 0, 0, for engaging said arm. Theother arm F is extended under the stem c" of the can-lifter and adaptedto force the same upward and thus raise the 5 same to bring the mouth ofthe filler into the top opening of the can as hereinbefore stated. Thereis a sufficient playorlost motion between the arm F and stem cto allowthe other rock-arm -F to move the push-bar -h back to its extreme outerposition without raising thelifter to an excessive elevation. e alsoutilize one of said rock-arms, preferably the arm F, for operating thepiston of the sirup-pump 1" which has its discharge nozzle P over thecan guide a between the can-lifter c and can-chute a. Said pump pistonderiving motion from said rock-arm by a pitman -R, which is connected tosaid arm adjustably lengthwise thereof, so as to allow the thrust ofthepump piston to be regulated according to the amount of sirup desiredto be introduced into the cans. Said adjustable connection may be madein various ways and is shown in the form of a longitudinal slot -F- inthe rock-arm receiving through it the bolt by which the pitman isconnected to said arm.

To regulate the thrust of the rock-arm F- so as to prevent it frommoving the can-pushing bar b beyond the desired distance toward thefiller, we attach to the frame a set-screw -for other suitableadjustable stop in the path of the said rockarm.

Beyond the filler A- is a can wiperd arranged to sweep across the top ofthe filled can and clean the same. Said can wiper is pivoted to abracket -I erected on the frame of the machine, and swings in ahorizontal plane and in an are extending transversely over thecan-guide. The said canwiper has extending from it an arm dwhich isconnected to a two armed lever-epivoted to the frame of the machine. Toa post -gon the bracket I is connected the upper end of a spiral springq', the lower end of which is attached to a sleeve, K, sliding on saidpost and connected to the horizontal arm of the lever -e which isthereby drawn upward and caused to hold the wiper (Z in its normalposition. To sweep said wiper across the top of the can we connect thevertical arm of the lever 1 to the manually operated lever O by a rod--ewhich passes freely through an eye in a stud-pin e-- attached to thelever C and has adjustably secured to its outer end a collar e"- whichis set in such a position as to permit suflicient lost motion betweenthe rod and lever to leave the wiper dormant during the first part ofthe rearward movement of the lever C and only actuate the wiper duringthe latter part of said movement of the lever which at the same timelifts to the filler the empty can broughtdirectly under it by thepushing bar b.

h denotes a stirrer which is arranged beyond the wiper and movablevertically to enter into the filled can and stir the contents thereofand subsequently withdraw therefrom. Two of such stirrers may beemployed if desired, as shown. We prefer to construct said stirrer of ahorizontal disk h' pivoted in and extending through the base'of thebracket I- and rigidly attached to a vertical shaft -tand pivoted at itsupper end to the said bracket and provided with a pulley jupon whichruns the belt -j'-, by which rotary motion is imparted to the shaft 2'.The body of this shaft from the disk h to the journal of the shaft issquared or otherwise made angular and upon the same slides vertically acollar -i' to which are fastened the stirring wires hwhich pass freelythrough apertures in the disk h and are preferably united or formed inone piece looped beneath the disk as represented in Fig. 5 of thedrawings. The collar-z"- is connected to the before described slidingsleeve -7a and the stirrer is thus also sustained normally in its raisedposition by the spring gand actuated simultaneously with the can-wiperd.

The operation of the described machine is as follows: The cooker -Bbeing in operation forces the cooked corn or other sub stance into thefiller A. The empty cans u 3 uto be filled maybe placed either singly orin a tier upon the platform l) of the pushing bar b-, the bottom canbeing surrounded by the ring a'. Then by swinging the lever C to therear as represented in Fig. 2 of the drawings the platform --b' iswithtlrawn from under the cans which then.

drop onto the guide a. The operator then throws the lever O forward andcauses the bearing 0- thereof to engage the rock-arm F- and push thesame forward as shown in Fig. 3 of the drawings. Said rock-arm carrieswith it the baribwhich pushes the bottom can to a position directlyunder the discharge-nozzle P- of the sirup-pump. In said movement theplatform b passes under the remainder of the tier of cans and supportsthe same. The operator then draws back the lever C- to its extreme outerposition, another can is thus allowed to drop onto the guide aand pushedforward by the next forward motion of the lever. Each can thusintroduced into the machines pushes along the cans in front of it, andin this manner the cans are passed successively to the nozzle P-, lifter-c, wiper (Z and stirrer h. The rearward movement of the lever -Coperates the pump P by the rock-arm --F- and pitman R- so as to forcesirup into the can standing under the nozzle P' and at the same time therock-arm F pushes up the lifter cso as to cause the discharge spout ofthe filler A to enter into the opening of the can seated on the lifter,and the wiper is drawn across the top of the filled cans and the stirrerentered and rotated in the farthest filled can by the lever C- drawingback the rod -e. There is sufficient play between the bearings 0-0' toallow the lever O to be swung forward a sufficient distance to releasethe rod e and allow the wiper d and stirrer -h to resume their normalpositions before causing thelever to actuate the can pushing bar b bythe rock-arm F.
